New 10 speed record ergo lever seems to "lock up", one out of 15 times, and not allow shifting up from small cog. (Unless, it seems, I pull the shifting lever towards me.)
Also sometimes downshift button gets locked up.
I realized that while taping the bar I moved the hood in such a way that could have interfered with down shift button, and I thought it being messed with could cause uptight locking. I corrected that, and the hood lays over the body fine.

Something is fouling the thumb button, not allowing it to come all the way up, causing the jamming..Tape under the lever somewhere around the thumb button mech/teeth??

i used to get the same problem when my stuff was new - on the small cog. seems the mechanism relies on a small amount of tension to "set it up" for the next click. i figured out that a quick tug on the downtube cable sorted it.
and now everything has some milage on it, the problem's gone away.

'ERGO lock' IS when something not allowing the thumb button to come all
the way

It ain't when you try to push one lever while the other is partially pressed, causing neither to move? That's an internal goings-on, not tape or other interference. I can reproduce it on any Ergo lever.

You are both describing the same effect. When the small lever is engaged for whatever reason the long lever won't shift. Holding one's thumb on it is indeed one way to engage the small lever, locking the mechanism. There was a run of shifters a couple years back with excess plastic flash occluding the return spring in the small lever. Same "lock"; trimming the excess material away freed the small ever to move normally back up .
Really these are so darn simple you can see nearly all the bits and how this happens by peeling back the cover. Take a look!

Like everyone said, check your bar tape. I always used to put a little bit of grease on the mech. teeth.
